What's next for Yahoo?

Apollo Global Management has not yet announced its plans for Yahoo, but there are a few possibilities:

* Yahoo could continue to operate as a standalone brand within Apollo's portfolio. This would allow Apollo to leverage Yahoo's existing user base and brand recognition to generate revenue.

* Yahoo could be merged with another company. Apollo could choose to merge Yahoo with another media company in its portfolio, such as AOL, or with a company outside of its portfolio.

* Yahoo could be sold to another company. Apollo could choose to sell Yahoo to another company, such as a private equity firm or a strategic acquirer.

The future of Yahoo is still uncertain, but the company has a long history and a strong brand, which could make it an attractive asset for any of these potential outcomes.
